I got word that an article I started writing last November has finally made it through all the editing and other stages and has been posted on-line. It covers how to use reflection and the CodeDOM to create a proxy for a web service. It also has a Windows application that uses the dynamically generated proxy and will allow you to call that web service. The URL to the article is http://msdn.microsoft.com/vstudio/default.aspx?pull=/library/en-us/dnvs05/html/CallWebServ.asp
